Application led December 7, 1925. Serial- No. 73,785.

This invention relates to improvements in presser foot attachments for sewing machines and a gage therefor- The principal object of the invention resides in a presser foot for use in the stitching of fabrics, when it is desired to conceal cords or other reinforcements within a hem for finishing urposes on garments or upholsterfbr accurately turning the hem by means of a gage supported from the presserfoot and which may be adjusted with relation to the needle slot in the presser foot for turning hems of dil'erent widths.

Another object of theinvention is to provide a presser foot which may be attached to sewingfmachines and used for var ious types of stitching, such as the plain stitch, piping,'loops and tucks. Heretofore, it has been the practice to use a separate presser foot for eaclr diferentstitch, which causes a loss of time when changing from one presser foot to the other. y

' Another ob'ect of the invention is to construct a` com ined'presser foot and gage therefor which lis simple in construction, inexpensive of manufacture and highly` e'ffcient for the purposeintended.

With these and other objects in view, lthe invention resides incertain novel construction and combination and arrangement of parts, the essential features of which are hereinafter' fully described, are particularly pointed out in the vappended claims, and

are' illustrated in the accompanying drawing, in whichz l Figure 1 is a perspective view of my improved presser foot and gage eshowing the gagein'anoperative position in full lines and` in an inoperative position in dotted lines.

Figure 2 is a transverse sectional view on the line 2- 2 of Figure l.

Figure '3 isa vertical longitudinal sectional view on the line 3 3 of Figure 1. 45

Referring more particularly to the drawing, the reference numeral 10 designates my a Ygage there-v adaptedv to be for. The presser foot 11 is carried by the presser foot bar of a sewing machine in the usualmannerand comprises a body portion 12 from which an angularly disposed foot 13 extends. The foot 13 is bifurcated as at 14 to provide a slot for the "passage 'of the usual reciprocating needle 15. 4 he furcations formed by the 'bifurcation in the foot constitute toes 16 and 17,

the toe 16' beingslightly longer than the toe 17. The construction thus far described is similar to an ordinary hemstitching presser foot,` but topermit the presser foot to be used for stitching a cord 1S firmly within a hem of a piece of fabric '19, I provide a longitudinal groove 20 in the underside of the toe 16. One edge ofthe groove extends in close proximity to the bifurcation 14 so that the needle 15 will stitchthe hem in close proximity strip 18. Although the groove 20 is shown as semi-circular in crosssection, it 'will be understood that-the same maybe of any configuration depending uponv'the shape of the reinforcement. For instance, the groove may be rectangular in cross section to accommodate the stays of a corset for stitching the stays to the fabric.

The gage 11 above referred to comprises an L-shaped arm or bracket 21 provided with a laterally extending rod 22 which passes through an opening 23 in an exten-` sion 24 carried by the body portion 12 of the to the cord or reinforcing presser foot. The rod 22 is free to slide l rod.

The free end of the arm 21 is flattened and carries a set screw 25 for threading engagment with a hem turner or gage 26. The gage'26 has a lug 27 extending `therefrom and whichl is adapted. to underlie the flatv end of the bracket and is provided with a' threaded opening' 28 for receiving, the screw 25.- When loosening the screw 25, the gageI may be removed from the bracket and a different style gage substituted therefor. The present gage has a're1atively` wide mouth portion 29 which tapers to al restricted portion 30, whereby the edge of thel fabric .may-

be turned over when fed beneath the presser foot. The gage 26 with respect to the presser'foot by the adjustment of the rod 22 whereby to produce hems of different widths.` When not in use, the gage may be swung up out of the screwed into clamping engagement with the l may be laterally adjusted way and held in such position' by the set screw 24 as clearly shown in dotted lines in Figure 1 of the drawing.

` What I claimed as new is r- 1. In combination with a presser foot for sewing machines having va rearwardly extending boss, a gage comprising an L- shaped supporting arm, means for adjustably supporting said arm with respect to said presser foot for movement toward or away from the same, said means including a laterally extending rod slidably mountedv in said boss, a clamping screw carried by said boss and engageable with said rod, and a hem turning member removably supported by said arm forward. of said presser foot.

2. A presser foot for sewing machines for enclosing a strip of material which is round in cross section Within the hem of a piece of fabric during the formation of the hem,

comprising a body portion, an angularly l disposed foot extending from said body portion and having a relatively short toe and ka spaced'relatively long toe, a longi- 'tudinal semi-circular groove provided in the underside of said long toe and extending approximately the length of thesame for accommodating the thickness of the material adapted to be enclosed within the hem during the formation thereof, and a guide adjustably supported with respect to said short toe for turning the edge of the fabric over the material prior to the passage of the short toe thereover.

In testimony whereof I have affixed my signature.
